Inkcazo:
I-Isophthalic acid yi-organic compound enefomyula i-C6H4(CO2H)2. Le solid ingenambala yi-isomer ye-phthalic acid kunye ne-terephthalic acid. Ezi aromatic dicarboxylic acids zisetyenziswa njengezinto ezizandulelayo (ngendlela ye-acyl chloride) kwiipolymers ezibalulekileyo zorhwebo, umz. Izinto ezingatshiyo zeNomex. Ixutywe ne-terephthalic acid, i-iso phthalic acid isetyenziswa ekuveliseni iiresins zeebhotile zokusela. I-poly benzimidazole ye-polymer esebenza kakuhle iveliswa kwi-iso phthalic acid.

Ukusetyenziswa
I-Isophthalic acid isetyenziswa njengesixhobo esiphakathi seepolyester ezingagcwaliyo ezisebenza kakuhle, iiresini zokugquma, iipeyinti ze-high solids, iijeli kunye ne-modifier ye-polyethylene terephthalate yeebhotile. Isebenza njengezinto ezizandulela izinto ezingatshiyo ze-nomex kwaye isetyenziswa ekulungiseleleni i-polybenzimidazole ye-polymer esebenza kakuhle. Ikwasetyenziswa njengegalelo lokuvelisa izinto zokukhusela ubushushu.
I-Puried Isophthalic Acid (PIA) isetyenziswa kakhulu njenge-intermediate ye-UPR esebenza kakuhle, ii-resins zokugquma, iipeyinti ze-high solids, ii-gel coats, kunye ne-modifier ye-PET yeebhotile.
